java实现绘制桃心(附完整源码)

以下是 Java 实现绘制桃心的完整源码：

import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class PeachHeart extends JPanel {

  // 定义桃心大小和位置
  private static final int WIDTH = 200;
  private static final int HEIGHT = 200;
  private static final int X_POSITION = 100;
  private static final int Y_POSITION = 100;

  @Override
  public void paintComponent(Graphics g) {
    super.paintComponent(g);
    g.setColor(Color.RED);

    // 绘制左半边桃心
    g.fillArc(X_POSITION - WIDTH / 4, Y_POSITION - HEIGHT / 4, WIDTH / 2, HEIGHT / 2, 0, 180);
    g.fillArc(X_POSITION - WIDTH / 4, Y_POSITION, WIDTH / 2, HEIGHT / 2, 0, 180);

    // 绘制右半边桃心
    g.fillArc(X_POSITION, Y_POSITION - HEIGHT / 4, WIDTH / 2, HEIGHT / 2, 0, 180);
    g.fillArc(X_POSITION, Y_POSITION, WIDTH / 2, HEIGHT / 2, 0, 180);

    // 绘制两个圆弧之间的矩形
    g.fillRect(X_POSITION - WIDTH / 4, Y_POSITION - HEIGHT / 4, WIDTH / 2, HEIGHT / 2);
  }

  public static void main(String[] args) {
    JFrame frame = new JFrame();
    frame.setSize(400, 400);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    PeachHeart panel = new PeachHeart();
    frame.add(panel);

    frame.setVisible(true);
  }
}

运行该程序将会显示一个红色的桃心形状。其中，`paintComponent` 方法用于绘制桃心的形状，`main` 方法创建一个 `JFrame` 窗口并将 `PeachHeart` 面板添加到窗口中。
